Sending triggered email using custom table

Hi Thomas.
Thanks for getting some time to answer.
So you’re confirming that I cannot send a triggered email using a custom table of email addresses.
The question is, can I use a triggered email with Twilio? I mean… if I can use a created template or if I have to create the HTML source and pass it to Twilio.

Other way could be to create vis API a contact and then use it to send triggered emails.
In this case, I’d like that WIX should not considered my created contacts as newsletter contacts to avoid sending posts to them. Do you know if a created contact via API receives ping of blog post?

Thanks a lot
